CORDER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 416,215, dated December 3, 1889.

Application filed August 19, 1-889. Serial No. 321,212. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN DRINKWA- TER, gentleman, a subject of the Queen of Great Britain, residing at No. 2 Eton Street, Richmond, in the county of Surrey, England, have invented an Improved Presser-Foot for Sewing-Machines, of which the following is a specification.

The object of my invention is to enable thick cordssuch as are used as edgings in upholstery-to be sewed by a sewing-machine onto fabrics without the stitching being visible. To effect this, I form the presser-foot of the sewing-machine with a longitudinal and nearly semicircular groove on its under side where it bears upon the top of the cord, and this groove is of such a size that the cord, when flattened out by the pressure of the foot, fits and fills the groove. The presser-foot is also formed with a notch at one side to permit of the descent of the needle. By these means I insure that the needle descends through the flattened cord close to one side of it and then through the fabric to which the cord is to be sewed. Consequently the part of the cord through which the needle passes is drawn down by the stitches and is held down closely to the fabric. When the cord is released from the pressure of the foot upon it, the cord resumes its original form, or nearly so, and overlaps the line of stitches. In this way the stitching which holds the cord and the fabric together becomes hidden. The cord may be used for hiding the junction of two pieces of fabric where they are stitched together. In this case the cord should first be sewed onto .one piece of fabric near its edge in the above manner, and then the other fabric sewed to the first close to the line of stitches by which the'cord is sewed to it. The fabrics while being sewed are face to face with the cord between them and a similar grooved presser-foot is used.

In order that my invention may be fully understood and readily carried into effect, I will proceed to describe the drawings hereunto annexed.

Figure 1 is a side elevation of the presser of a sewing-machine with its presser-foot. Fig. 2 is an opposite side elevation. Fig. 3 is a front elevation. Fig. 4 is a front elevation partly in section. Fig. 4* is a similar view in which the positions of the table of the machine, the cord, and the needle also are indicated. Figs. 5, 6, and 7 show, respectively, a side elevation, plan, and under side view of the presser-foot separately.

to is the stem of the presser.

b is the ordinary lifting-cam.

c is the socket part of the presser-foot, fitting the lower end of the stem to.

d is the screw by which the foot is secured to the stem of the presser.

e is the groove for the cord, and f is the notch by which the needle descends. *The groove 6 is curved approximately in the arc of a circlethat is to say, the groove is segmental in cross-section less than a semicircle. By this arrangement the cord to which the resser-foot is applied is flattened out and its edge presented under the needle-notch, so that the needle may pass through the cord as well as the fabric to which it is secured.

In Fig. 4*, g is the cord flattened by the pressure of the presser-foot, and h is the line on which the needle works. The foot, it will be seen, pinches the cord down and forms a thin flattened edge for the needle to work upon. At the same time the foot allows the cord to spread laterally while guiding it by its outer side, so that it cannot escape from the needle. \Vhen a cord of another size is to be worked, the foot is changed for another similar foot, but suited to the dimensions of the cord. \Vhen joining a second fabric to one which already has a cord sewed upon it, the second fabric is laid face down. over the first with the cord between. Thus the fabrics are passed through the machine, a press er-foot such as above shown and described and of suitable size being employed. When the work comes from the machine, the cord will be found to cover the line of stitches.

W'hat I claim is A presser-foot for sewing-machines, having a longitudinal groove e on its under side, segmental in cross-section, but less than a semicircle, and also formed with a notch or aperture f at one side of the groove, but between its opposite ends, whereby in operation the sewing-machine needle may pass through the flattened edge of the cord.
